A new report from the commission released over the weekend identified 22 senior officials who had "deliberately refused" to cooperate with its asset verification team, including some who allegedly flouted notices to appear.

The commission also accused three officials of "unexplained wealth accumulation," including a former minister who allegedly could not account for $100,000.

President Ellen Johnson Sirleaf declared war on corruption when she took office in 2006. Last year, she suspended 46 officials for failing to declare assets, including a son who works at the Central Bank.

Although Liberia's position on Transparency International's Corruption Perceptions Index climbed 16 spots to No. 75 last year, many Liberians believe official corruption is increasing as state institutions like the police force expand their presence.

In a report released in August, Human Rights Watch said "rampant" police corruption denied many Liberians access to justice because kickbacks were prohibitively expensive.

The cases of "unexplained wealth accumulation" involved one official who declared more than $300,000 in the bank despite earning a monthly salary of just $2,500. A police official earning $704 per month could not explain a one-time deposit of $33,850, according to the commission's report.

And former Internal Affairs Minister Blamoh Nelson allegedly could not account for $100,000 an accusation Nelson denied on Monday in an interview with a local radio station, saying he had provided "sufficient and accurate information."

"So I don't understand their doubts. They did not uncover anything. I gave them what they wanted, and there is a use of wrong words here," Nelson said.
